ALLEN PARK -- The Detroit Lions have ruled out right tackle Corey Hilliard for Sunday's game against the Dallas Cowboys, while tackles Jason Fox and Riley Reiff are questionable.

Detroit could be perilously thin at the position for the week.

Hilliard suffered a knee injury last week against Cincinnati and hasn't practiced since. Reiff, who suffered a hamstring injury in the game, has practiced on a limited basis the past two days and seems like a good bet to play.

Fox rejoined the team this week after missing the past two games with a knee injury of his own. His return would be a major boost for an offensive line that is hurting at the tackle position.

Undrafted rookie LaAdrian Waddle and midweek acquisition Barry Richardson are the only healthy tackles on the team.

Tailback Reggie Bush was listed as probable, despite missing practice Friday. He was seen with an ice pack on his upper right leg, but insisted he will play against Dallas. There's no reason to believe he won't.

Receiver Nate Burleson (forearm) was ruled out earlier in the week.

Everyone else -- including Calvin Johnson -- is probable.

Perhaps the most notable injured player doesn't play for Detroit at all. DeMarcus Ware, the Cowboys' Pro Bowl defensive end, is listed as doubtful to play against the Lions.
